Individual Mexican physicists have been working on experiments at CERN since
UA1 (in the 1980s). Various institutes are participating in
ALICE , working principally
on the trigger system and in connection with cosmic-ray physics, and other institutes
have joined CMS

In 1998, a Co-operation Agreement between the Consejo Nacional de Ciencia y Tecnología (CONACYT)
of the United States of Mexico and CERN was signed in order to further develop the scientific and
technical co-operation in high-energy physics. An Agreement has been signed with the National Autonomous
University of Mexico to co-finance working exchange visits. Contacts with Mexico have been strengthened
by its participation in HELEN (2005-2009) and EPLANET since February 2011.

The second CERN-Latin American School of High-Energy Physics was held in Mexico in 2003.

On the occasion of the LHC inauguration in October 2008,
the Joint Director for Scientific and Academic Development of Consejo Nacional de
Ciencia y Tecnología (CONACYT) visited CERN.

After the visit of a large Mexican Delegation, in September 2013, a Protocol to the 1998 Co-operation Agreement
was established on 29 October 2013, with the aim of facilitating the participation of CONACyT and other Mexican
Institutions in our Programmes.
